VEHICLE-AXLE.

Specification of Letters Patent.

Patented Aug. 13, 1912.

Application filed May ,4, 1912. Serial No. 695,052.

To all whom it may oon/cem:

A Be it known that I, EDWIN E. Anxonn, a citizen of the'United States of America, residing at Detroit, in the county/of lllayne and State of Michigan, have invented certain new and useful Improvements in Vehicle-Axles, of ,Which the following is a specication, reference being had therein to .the accompanying drawing The invention relates to vehicle drive axle Iconstructions of thattype in which the drive gconnection between the wheel and the axle A shaft' is formed by the head or flange on the outside of the Wheel hub. Vlith such constructions it is usual to detachably bolt the driving head or flange to the Wheel hub so as to permit the removal of the axle shaft uithout disturbing or loosening the Wheel and hub assembly.' The bolts' which are employed for securing the driving flange to said hub are also utilized to secure the Wheel hub assembly by passing through the hub flange, the intermediate spokes and an inner llange,` usually the head of the brake drum, and .clamping said parts rigidly together. Thus in order to accomplish this desirable feature a special construction of boltlor stud is required having an interina,

diate. head or clamping collar and threaded opposite ends. y n

It the object of the present invention to dispense with the use-of a specialbolt and to aeconipl-ishthe dual andy independent clamping of the hub assembly and driving flangeeonstruction. 4 v

It is a further object to obtain a stronger connection and particularly one'whichoifers increased resistance tov the shearing stresses onlthe fit, due to the transmission of the driving o'rque froml the axle to the wheel. In thedrawin s,-Figure l is a'c'entral longitudinal section through a portion of the axle Wheel and brake head;` Fig. 2 is an elevation thereof.

A is the axle case of. any suitable construction, B is the wheel journaled upon the end of the'axle, C is the brake drum secured to the inner side of the wheel, D is the axle shaft Within the casing A, and E is the torque head or driving flange which connects the shaft D with the Wheel hub.

To secure the Wheel hub assembly proper I employ an ordinariT bolt F having'a head vGr and a threaded eno portion H. vThe head G is arranged on the inside of the Wheel and engages the .brake -drum G.

I is a nut engaging the threaded portlon ll of the bolt F and bearing against the outer face of the hub flange K to clamp the hub assembly together. l` his nut l is preferably circular in section having a conical inner face J which fits a corresponding conical recess in the hub flange K of the Wheel. The outer portion of the nut projects bcyond the flange K and engages an aperture L in the head E. Thus the nut I in addition to its function of clamping the brake drum to yt-he Wheel, constitutes a reinforccment for the bolt F at the joint between the flange K and head E, increasing the cross sectionand thereby further resisting shearing stresses. i

For detachably securing the driving head or flange E to the Wheel a second nut M is arranged to engage the outer project-ing end of the threaded-portion H of the bolt, which nut bears against the flange of thel ead and clamps the salne in position. VVhene er it is desired to remove .theshaft D the bolt M may be detached, permitting the Withdrawal of the head E and Without. disturbing or .loosening the connection between thebrake drum and the Wheel.- i

What I claim as my invention is: v

' 1. The combination with a lvehicle-Wheel having a brake drum at one side thereof and a torque head at the 'opposite side thereof, of a securing means for said parts comprising abolt extending through the Wheel and having a threaded outer end, a nut engaging the threaded portion .of said bolt and'clamp- ,ingsaid brake drum, and a. second nut engaging the outer end'of said threaded portion and clamping said torque head.

'2. The combination with a vvehicle lWheel, a brake drum arranged on one side thereof and av torque head on the-opposite side, of a bolt forming a common clamping lmeans for f said head having a threaded portion at its outer end, a nut en aging the threaded portion of said boltV or clamping said brake drum', the outer portion of said nut lextending into an alined vaperture in said torque head and bridging ythe joint between said head and the Wheel, and a second nut engaging the threaded portion of said bolt for clamping said torque head. y"

3. The combination with a vehicle wheel having a brake drum at one side thereof and 'a torque head on the opposite side, of a bolt having a headed innerend and a threaded cuter-end engaging the securing portion ofy loo .` slid brake 'drum and extending through said wheel, a nutengaging the threadedportion. of said bolt on the outer side .of said wheel and having a clampinglengagement 5 therewith,`s`aid nutl bridging the' joint be-.-

hmd, a nut engaging-the thieaded portion .of said bolt bridging the joint between said torque head-,and metallic hub .and having a clamping bearing on the latter, and a second im nut engagin the outer threaded portionjo'f said bolt an clamping sai'd-'torque-he'ad The combination with a vehicle/Wheel har; g a metallic hub, of-a brake drum on' the side oisa'id wheel, a torquehead @en .the enter side of said wheel bearing said metallic hub; said hub and torque head having registering apertures, al

halt through' said wheel having a head at its inner' end engaging said brake 30 a threaded ou'ter end passing ination' with a vehicle Wheel.

vhead on the outer side of said Wheel the ward through said metallic hub and torque through said,V registering'- apertures,V a .nutf'z engaging the threadedportion of .said bolt Within said registering apertures and'having a olarnping bearing O n'the metallic, hub,'
